| 摘 要： | 定位是无线传感器网络中最重要的功能之一。通过利用一个移动信标节点（装备GPS或提前设定了移动路线）来帮助各个未知节点进行自身定位。信标节点周期性的发送自己位置信息给周围的未知节点,未知节点通过非测距技术估计自身位置。信标节点的移动路径在文中也进行了探讨。仿真结果说明了本文方法的有效性。

| Abstract: | Localization is one of the most important issues in wireless sensor networks.Several approaches,including range-based and range-free,have been proposed to calculate positions for randomly deployed sensor nodes.In this paper,a single mobile anchor(with GPS or pre-defined moving path) is used to help sensors to accurately discover their positions.The mobile anchor periodically broadcasts its location while it moves around or through a sensor field.Each sensor nodes compute their position estimate based on the... |
